Y Application filed August 1,

T all whom it may concern:

,Be it known that I, CriA'aLEs F. PYM, a' citizen of'Canada, residing atEsseiz; the

Province of Ontario; Canada, have invented an Improvement in Lastin-Machines, of

which the following description, in' connec tion with the accompanyingdrawings; is a specification, like letters j'on the drawings" 7representing like parts.

more'at length in the course of the following" description, referencebeing had to 'the'-'accompanying drawings, in which I"have'" shown ation;

preferred embodiment of my inven In the drawings: Figure Us aperspective view of a lasting machine provided witl'i my vation, thelower part beingin section, show improvements;'Figs. -2 and 3 arefragmen' tary details in top plan and si'de'elevation of the fiattenerwhichoperates with the wiper of the machine and with the lasting jackfor permitting the shoe to be swung around and handled readily; Fig. 4is a central longitudinal section view of the lower portion of the jacksupport; Fig. 5is a view in front eleva tion thereof; and Fig. 6 is aview in front eleing the upper part of'the' jack and illustrating itsmovement in dotted lines. 1

It will be understood that my'imnrovements may be used with any usualfasting machine, the form herein shown comprising a head 1 on a suitablepedestal 2 provided with tack driving mechanism, consisting of a by anarm 6 and eccentric 6 the tacks a stirrer rod 8 and wormwhe'el 9andwornr 10 from a shaft 11."

Cooperating with this fea-11o turein steadiness and aiding in'holdmg the shoe in proper osition asit is turned and shifted about, an also aiding in flatteningthe crimedleather, is 'a nozzleffoot or. flattener bloc 42, clamped immovably atthe j e '3 by any suitable iewer, end of the nozz meansyas by a'scre'w43. The crimper 12 is bifurcated to straddle this fiattener42, therei bycooperating therewith to wipe down and lie-crimp. the upper. Not onlydoes this flatform depth, and it helps to make a flat seat and't o're'vent the upper from being trapped or'ca when 't e upper is short atthe seat, as ejquentlyhappens. Undersuchcircumstances T I, it has beencommon heretofore for the leather to catch between the nozzle and wiperand either tear the leather or bend-- or break the nozzle. 4 I can bestdescribe the operation of my inventionin connection with lastingheelseats. When the jack moves down away from the nozzle and wiper, due tothe upward movement ofthe crank 29, which lowers the rocker so arm 27and thereby depresses the jack, the operator feeds the shoe forward byswin ing t e spindle slightly on its pivot 17, the ack immediately risesand forces the shoe against i the nozzle-footrest or flattener 42 with a3'5 stro force, operating to flatten the seat and crow and press theleatherdownstrongly a ainst the T hel s the wiper with its work,preventing the ormation o a ridge in the leather be 40 tween the edge of{t e shoe and last and the nozzle. The flattener 42 spreads ordistributes the pressure of the jack and makes the work much more even.It'cooperates with v the constant up=and-down motion of the jack 45 tohammer vthe heel seat, as well as smooth and iron the same and preventthe trapping of the leather, already mentioned, and it gives a broadbearing "on' which to swing and move the shoe, tending to help maintainthe shoe in roper position in connection with the spin le support 15.

' If the operator desires to move the shoe temporarily nearer or fartherfrom the wiper and tack driver, he can do so simply by swinging theentire jack in opposition to the s ring-held arm 36, without changingthe 0 amp 40. The latter is adjusted to suit different sizes of shoesand styles of work, and is for the purpose of giving steadiness ofmovement and aiding the operator in directing the Patent is, l

t betweenlt e nozzle andthe w1 er' ast' on which it is beinglastedmovements of the shoe. The jack is always in its highest positionor point of travel when the tack d'rlv'en, at which time the shoe isheldfirmly a ainstthe nozzle'and flattener, theresult being that thetacks are driven 6 into the shoe evenly "and are properly and m idlyclenched. I d Y aving described my invention, whatI claim as new anddesire to secure by Letters 7 1. In a lasting machine, a tack driver, areciprocatory wiper, and lasting jack, and operating means thereforoperated in timed relation to the tack driving, said lasting jack andits operating means pressing the last and. 7 shoe vertically up at thetime of tack-driving against the wiper and tack driver in opposi-' tionto their downward pressure on the bottom of the last, the aforesaidmechanism including means for hammering verticallythe 8 crimed leatherdown u on the bottom of the ast' as it is being aid by .the wipingmovement and pressure of said wiper.

2. In a lasting machine, tack-driving mechanism and its operating means,awiper, 8 operating means therefor operating in timed relation to thetack-driving mechanism, to

engage the shoe when a tack is driven, a jack for holding the shoe withrelation to said tack driving mechanism and wiper, and 9 automatic meansfor forcing said jack and its shoe strongly against said Wiper each timea tack is driven. I v

3. In a lasting machine, tacking mechanism including a nozzle, lasting,mechanism 9 including a lasting jack, means forimparting an up-and-downfeeding movement to said jack with relation to said nozzle, anda'laterally extending flattener block fast on the lower end of saidnozzle for cooperating with 1 said lasting jack in flattening theleather and steadying'the work.

4. In a lasting machine, a tack driver provided with a nozzle, areciprocating wiper operating in line with said nozzle, said wiper 1havin a bifurcated crimping end, and a narattener block extendingrearwardly over the edge of the last in line with said wiper to rest onthe shoe between the proj ecting endspf the wiper as the latter recipro-1 cate, for preventing injury to the leather and aiding in flatteningthe crimps of the leather and steadying the work.

In testimony whereof, I have signed my name to this specification, inthe presence of 1 two subscribing witnesses.
